CAP-SPINNING FRAM Application filed J'u1y'13, 1922. Serial: No. 574,676.

T 0 all whom it may concern:

Be it known that I, JOSEPH H. JONES, a citizen of the United States,residing at Winthrop, in the county of Suffolk, State b ofMassachusetts, have invented a certain new and useful Improvement inGap-Spinning Frames, of which the following is a specification,reference being had therein to the accompanying drawings.

My invention comprises improvements in cap-spinning devices of the classin wh ch a live cap and the spinning element (spindle or bobbin) withwhich it cooperates revolve in unison, or substantially in unison. I

The invention comprises improvements in connection with the so-calledpivot, i. e., the element which in devices of the class referred toserve to afford vertical support to the revolving cap and to control thesaid'cap during'the traverse by means of which the yarn 1n process ofbeing spun is distributed upon the spinning element, as it is woundduring the spinning operation.

The invention provides a novel arrangement of a so-called pivot incombination with a live cap. Also special means for mounting the pivotand supporting it in working relations with the cap with which itcooperates.

An illustrative embodiment of the features of the invention isillustrated in the accompanying drawings, in-which,--

F ig. 1 is a view ofcertain parts of a spinning frame having the saidillustrative embodiment combined therewith, the parts being viewed at anangle.

Fig. 2 is a plan view showing two sets of bobbins, live caps andso-called pivots, and a portion of the pivot supporting rail.

Fig. 3 isan elevation of portions of a spindle, a bobbin with its yardload, a live cap cooperating with said bobbin, a socalled pivotcooperating with thersaid cap, and a portion of the pivot supportingrail.

Fig. 4 is aview of certain of the parts shown in Fig. 3, showing themounting or support for the so-called pivot in longitudinal verticalsection. 3

Referring first to Fig. 1: Such figure shows at 1 a portion of athread-board having hinged thereto at 2 a block 3 (one of the usualseries) carrying a'guide 4 for the yarn a: between the front rolls andthe twisting devices, 5 being a spindle-railhaving mounted thereon inusual manner-a ear1ng'.-support spinning-spindle 71., At 9 is a quill orbobbin mounted upon the spindle-blade, and at 91 a load of yarn whichhas been spun and wound upon the said quillor bobbin. gAt 10 is arevoluble or live cap cooperating with the said quill or. bobbin. Aso-called pivot or cap-controlling wheel is shown at l1. 12 is themounting'for. the said pivot orv cap-controlling wheel, 13 being a railto which the base 121 of the said mounting is fitted. j

s usual in the case of devices of this type the-cap 10 has a bushed holethrough itshead, with. a central opening so proportioned that thebushing has a close but easy sliding fit upon the blade or barrel ofthe; spinning element to which the cap is applied, such element being inthis instance the quill-or bobbin 9. The said sliding fit permits vtheca to gravitate downward upon the said .b adev or barrel until the capis supported vertically through engagement of its flaring peripheralportion- 101 with a the engaging. portion of the associated pivot 0rcap-controlling wheelll. The said sliding fit also permits the traversemovements of the cap up and. down upon the said blade or barrel whichare required to take place for the distribution of the twisted yarnsuponsuch blade or barrel in being wound thereon. The cap is caused torevolve through light frictional contact between the periphery. of thesaid blade or barrel and the inner surface of the bushin in connectionwith the hole through the head of: the cap. 1 Referring now to thefeatures of the invention: The pivot or cap-controlling wheel 11 isarranged to rotate in a -plane at an anlower portion of the pivot orcap-supporting wheel is located adjacent the lower edge or lip; f thecap, as appears in Figs. 1 and 3.

referably, the lower portion of the pivot or cap-supporting wheelextends generates'currents of air also movlng oppositely. These currentsof air act against the portion of the yarn being spun which extendsaround the lower edge or lip of the cap to the spinning element, so asto offer a slight resistance to the revolution of such portion ing wheelis supported of the yarn in unison with the spinning element, therebyproducing what is termed drag of a character which promotes winding ofthe yarn upon the spinning element. This improves the spinning operationand facilitates the production of a softer yarn than the earlierarrangement of revoluble caps and their supporting pivots.

A second feature of the invention is the employment of a supportingbearing of ball or roller-bearing type for'the pintle 111 of the pivotor cap-supporting wheel. In the present instance I have shown aroller-bearing, although as will be obvious to those skilled in the artsof spinning and ball roller-bearings, ball-bearings may be used in placeof the roller-bearings. In the illustrated instance the mounting orsupport 12 is of sufficient internal dimensions to accommodate a seriesof anti-friction rolls 112, 112, etc. Fig. 4, which are engaged at theiropposite ends in notches in a pair of cagerings 113, 113, the assemblageof rolls and rings constituting a cage. The pintle 111 of the pivot orcap-supporting wheel is fitted interiorly within the circular series ofrolls and revolves therein, the cage being itself revoluble within themounting or support 12. Thereby the pivot or cap-support- I verticallyand the said wheel in turnis enabled to afford support vertically to thecap with which it cooperates. To take care of the end thrust which isoutward away from the axis of the spinning element, I employ a ball 114,

Fig. 1, which is disposed properly crate with the outer end of thepintle. At 115 is a coil spring located in a pocket at the outer end ofthe mounting or support 12 and confined between the outer end wall ofthe said pocket and the end-thrust ball 11 1. I use this spring to giveayielding and cushioning action, and to press the pivot axially tomaintain its lateral engaging edge in engagement with the flaringportion of the cap. At 116 is a split ring of wire occupying a groove inthe pintle and serving the functions of (l) preventing the tocoopwithdrawal of the pintle, and (2) of a splash ring to cause oilworking along the pintle toward the so-called pivot or wheel at theinner end of the pintle to flash off under centrifugal action, wherebysuch oil is prevented from passing out at the inner end of the bearingsupport.

To provide for radial adjustment of a pivot, the mounting 12 is madeseparate from base 121, and provided with a foot 122, having a slot 123for the stem of a screw 12 1 which attaches the mounting to the base.This slot permits the said radial adjustment. By means of suchadjustment the height of the cap above base 121 may be varied as foundnecessar-v lVhat is claimed as the invention is 1.
